Fig. at is a plan view of the bottom of the housing of the machine; and

Fig. 5 is a front elevationof the staple securing and straighteningmeans.

Referring now to the drawings in detail, 1 designates the base of mypmachine which. base may be of any desired shape and is provided withpads 2. Mounted upon the base 1 is an anvil 3 which is adapted to beengaged by the ends of the prongs of the staples during the clinchingoperation. Mounted upon the b-ase 1 and preferably, though notnecessarily, pivoted thereto is a housing 4:, which in the presentinstance is shown pivoted to the base 1 at 5.

The housing immediately above the anvil is provided with a guideway 6for the plun ger 7 of the machine and with a guideway 8 for the staplesecuring and straightening member 9 hereinafter to be referred to in de-The plunger 7 carries a coil spring 10, the lower end of which isadapted to engage the upper part 11 of the housing, the upper end ofthis spring being engaged by a cap 12 by which the machine ismanipulated.

The staple securing and straightening member 9 already referred .tocomprises a comparatively thin plate provided with legs 13 and 14, whichplate isadapted to slide 8 in the housing of the machine. The upper partof the staple securing and straightening member 9 is provided with anelongated slot 15 through which a'small screw 16 is adapted to pass andwhich screw is secured to the plunof the machine. It isto be understood,however, that the slot 15 just referred to is of larger dimensions thanthe screw 16 so that the staple securing and straightening member mayhave movement relatively to the plunger: '7. The upper part of thestaple securing and straightening member 9 is provided with laterallyextending lugs 17 and one end of a coil spring 18 which is carriedwithin the plunger spring 10 already referred to is adapted to rest uponthis end of the staple securing and straightening means, the other endbeing engaged byv the cap 12 already referred to. r

From the description thus far given it will be seen that I have provideda plunger and a staple securing andstraightening member in a housing,these two members, that is to say the plunger and the staple securingand straightening member, being so mounted as to be reciprocatedvertically in the housing of the machine, the plunger and the staplesecuring and straightening member having movement parallel to each otherand being movable at certam times independently of each other.

This arrangement is provided so that the staple securing andstraightening member may move down to staple-securing position beforethe plunger reaches that point in its travel where the staple is out offand the forward end of the strip being fed through the machine. I

It will be seen also that I have provided springs for each of thesemembers so that they will automatically return to their initialposit-ion, that is to say, to the position shown in Fig. 1.

Secured to the housing of themachine in any suitable manner is a memberwhich I shall hereinafter term a knife designated 19. This member isadapted to receive a strip of staples which are fed into the machinefrom the rear thereof, that is to say from the right-hand end as viewedin Fig. 1 and to be engaged by the body portion of the strip of staplesas distinguished from'the ends of the prongs of the staples, and tocooperate with the plunger 7 and the staple securing and straighteningmember. 9 so that when the parts are moved to the position shown in Fig.2 for example or just slightly further, the forward staple of the stripwill be out off by the plunger, the staple cut off being held up to thistime in position for the cutting operation by the staple securing andstraightening member and as will hereinafter be pointed out, being thenstraightened and,-so to speak guided during the driving and clinching ofthe staple.

The plunger 7 is which isadaptel to be straddled by the legs 13 and 1 1of the staple securing and straightening member, this lever 21, formingpart of what I shall hereinafter term a combined feeding means andback-stop. This lever 21 is provided with a pair of lugs 22 and 28between which the lug'20 is adapted which lugs are at times engaged bythe lug 20 so as to rock the lever 21 about its pivot. Secured to onearm of the lever 21 is another lever 2a, the levers 21 and 24 togetherconstituting a combined feeding means and backstop for the staple. Thelever 2 1- at its rear end is provided with a spring 25 passing aboutapin 26, the other end of the spring cooperating with the pressure lever27 to be hereinafter referred tomore in detail.

The front end of the lever to engage the strip of staples at a pointbetween adjacent prongs thereof and when the strip is in position forthecutting operation the front end 28 of the lever 24 will be in engagementwith the strip of staples between the third .and fourth staples of thestrip. YVith the front end 28 of the lever 24 in this position rearwardmovement of the strip of staples is prevented.

The pressure lever 27 already referred to is pivoted in the housing ofthe machine at provided with a lug 2O lug cooperating with a.

to be reciprocated and 2 1 is adapted 29 and cooperates with the spring25 already referred to, to merely hold the strip of staples down againstthe top of the knife 19. By reason of the provision of the combinedfeeding means and back-stop already described, the pressure plate 27 isfree of teeth.

The locking member or lever 30 is pivoted at 31 to the housing of themachine and is adapted to engage the rear end of the pres sure lever 27and in the position shown in Fig. 1 the parts are in position forautomatic operation of the machine. If it be desired, however, to removea stripof staples from the machine for any reason whatsoever, or tosubstitute a new strip of staples or to operate the machine'by hand asdistinguished from automatic operation of the machine, it is merelynecessary to swing the locking lever 30 to its extreme left-handposition, which movement of this lever will lift the pressure plate 27and also the lever 24 so as to permit of an unobstructed movement of thestrip of staples for any reason whatsoever.

In operation the locking lever 30 is preferably moved to its extremeleft-hand position to raise the pressure lever 27 and the lever 24upwardly and a strip of staples 32 is then fed into the machine with theprongs straddling the knife ,19 and the body portion of the stripresting upon the upper surface of the knife, the strip being moved intothe machine until the front end thereof cngages'the side 33 of the guide6 for the plunger 7. The locking lever 30 is then moved to the positionshown in Fig. 1.

It is to be understood, however, that if desired the lever 30 may beleft in the position shown in Fig. 1 in loading the machine as the stripof staples may be stiff enough to permit of the strip being forcedbeneath the pressure plate 27 to the position above described. Severalsheets of paper or other material which itis desired to staple 'may thenbe inserted upon the anvil 3, the frame 4' of the machine being rockedslightly about the pivot 5 for this purpose. The cap 12 is then moveddownwardly to carry the plunger 7 and the staple securing andstraightening member downwardly also.

he staple securing and straightening member 9 at the beginning of thismovement is slightly in advance of the plunger 7 so that the legs of themember 9 will enter between prongs of the strip before the moveddownwardly snfficiently far to cut off 11 this I am enabled to theforward staple. By securely hold my staple in position for the cuttingoperation. As the plunger 7 and the member 9 continue their downwardmovement the plunger Wlll cut'the forward staple .from the strip and assoon as this forward staple is cut off it will be forced by right asviewed in Fig. '1 and this the front end 28 of the l by the the staplefrom the strip member 9 effectually prevents any forcmg'of the stapleout of 1 ts proper position or any bending of the in proper position sothat the staple ways be driven will al home and clinched. This preventsclogging of the machine for it will be obvious that should a staple bebent in being cut off and driven through the paper, that the machinewill be clogged and that the papers or other material will be improperlystapled. Should the machine become clogged it would necessitate theremoval of the strip of staples and waste of the entire strip. 7

Still referring to the operation of my machine, -it will be seen that asmoves downwardly due to and finally it will engage the lower lug 28 onthe lever 21 forming part of the combined feeding meansand back-stopabove referred to. his engagement of the two lugs will cause the lever21 to be rocked about its pivot to carry the lever 24 to the of thelever 24 takes place before the first staple of the strip is cut oil.The lever 24 is moved to the right or rearwardly until ever engages astrip the third and fourth and will remain in this the remainder of thedownward movement of the plunger 7 and the staple securing andstraightening member 9. It will be seen, therefore, that not only is thestrip of staples securely held during the cutting operation and that-notonly is the staple cut off properly straightd and guided, but after theforward staple is cut off rearward movement of the strip of staples isalso prevented; After the plunger 7 and the staple securingstraightening member limit of their movement downwardly, that in Fig. l.movement of the plunger 7 and the staple securing and straighteningmeans 9, the lug 20 carried by thev plunger will engage the lug 22 ofthe lever 2l-to rock the lever in' movement ward staple of wall of theguide 33 for the. plunger.

the opposite direction to which it was rocked on downward movement ofthe plunger. This movement of the lever 21 will carry the lever 2eforwardly, that is to the left, as viewed in Fig. 1 and inasmuch as thefront end 28 of this lever is in engagement with the strip of staplesbetween the third and fourth staples thereof, the strip will be fedforwardly until the forthe strip will engage the The parts are now inposition for another Sta-- pling operation.

From the foregoing it will be seen that I have provided a combinationbinding machine wherein means have been provided having movementparallel with the plunger of the machine for securing and straighteningstaples during the staplingoperation so that clogging of the machine isprevented and so that a proper driving and clinching of the staples isassured.

It will be seen also that I have provided a combined back-stop andfeeding means for the strip of staples whereby the strip of staples willalways be fed forward properly and whereby rearward movement of thestrip is effectually prevented.

It will be seen also that I have provided an improved pressure platewhich is adapted to maintain the body portion of the. strip of staplesin engagement with the knife and which pressure plate by reason of myimproved feeding means and back-stop is free of teeth. 7

It will be seen furthermore that if desired I may raise the pressureplate and combined feeding means and back-stop out of their normalposition so as to operate the machine by hand if desired, this beingdesirable at times when it or desirable to employ longer or shorterpronged staples than the machine happens to be loaded with.

It will be seen also thatmy machine is of operating with. staples, the

capable. prongs of which may be of varying lengths, thereby avoiding thenecessity ofmanufacturing or furnishing a specific length of prong thatmay be used.

WVhile I have described a specific em-- bodiment of my invention it isto be under stood that changes may be made in the details thereofwithout departing from the spirit and scope of my invention.
